Quarterback Luke McCown had a perfect night for New Orleans and kicker Derek Dimke made two field goals, but the Saints couldn’t hold off Tyrod Taylor and the Ravens in a 22-13 loss on Thursday night at the Mercedes-Benz Superdome.

The Saints’ lone touchdown came on a 2-yard pitch-and-catch from McCown to running back Travaris Cadet, who also had three carries for 11 yards.

Ryan Griffin, who has battled McCown for the backup quarterback job throughout the preseason, finished 11 of 21 for 126 yards.

Meanwhile, the Saints defense struggled to contain Ravens’ second-string quarterback Taylor in the first half. Taylor completed 10 of 17 pass attempts for 105 yards and a touchdown before entering the locker room at halftime.

What You Need to Know

Robinson struggles: The cornerback position could be one of the Saints’ primary weaknesses on defense in 2014, and Patrick Robinson’s performance on Thursday night didn’t help dispute that claim. On the first drive of the contest, Robinson found himself opposite Ravens’ receiver Kamar Aiken, who proceeded to torch Robinson for 40 yards on two catches. Robinson also struggled against Baltimore receiver Deonte Thompson before exiting the game for good in the second quarter.

Pierre Warren makes his mark: With Kenny Vaccaro and Jairus Byrd on the roster, breaking through as a young safety in New Orleans will be quite the challenge. That being said, undrafted rookie Pierre Warren made a nice impression on Thursday night, intercepting Ravens’ quarterback Tyrod Taylor with a leaping pick in the Saints’ end zone. He also collected four tackles.

McCown perfect: Saints’ backup quarterback Luke McCown got the start in New Orleans’ fourth preseason game, and he made a strong case for the No. 2 spot on the depth chart behind starter Drew Brees. McCown finished 4 of 4 for 29 yards and a touchdown to running back Travaris Cadet.

Bailey injured: After finding limited play in the first quarter, Saints’ veteran cornerback Champ Bailey was examined on the sidelines after suffering an apparent hand injury. Bailey had his finger taped, and reports surfaced saying he may have dislocated his finger. The injury did not appear serious.

Dimke handles kicking duties: Coach Sean Payton gave veteran kicker Shayne Graham the night off, giving backup Derek Dimke the chance to impress. And impress he did. Dimke finished 2-for-2 on field goal attempts while also making his lone extra point attempt.
